What are VPNs? Definition, Benefits, Strengths and Weaknesses

What are VPNs? – Currently, VPN is being hailed in the process of surfing the internet network. In fact, there are many different types of VPN available and users only have to choose according to their needs.

Even when cases of theft of personal data in the digital world are rife, VPNs are said to be a safe solution for such cases. Is that true?

Then, what exactly is a VPN? How does a VPN work so that it can be called “safe” for its users?

So, so that Sinaumed’s knows the answers to these questions, let’s look at the following explanation about VPNs!

Understanding VPN

VPN stands for Virtual Private Network , aka a secure internet network connection for its users. Through a VPN, the access that you give to any website can run securely and privately , namely by changing the connection path through the server and hiding any data exchange that occurs.

How does that mean?

Now, a VPN connects a smartphone (can also be a PC or tablet) to another computer somewhere connected to the internet, so a VPN can be useful for “permissions” in browsing the internet to use a computer internet network.

So, if the computer ( server ) is in a different country, then the internet connection that you use adjusts to the VPN from that country. A VPN can also be useful for accessing things that you previously couldn’t access from your country.

In ancient times, VPN became a service that was often used by companies or organizations in an effort to protect their data. However, now with the development of the times, VPNs can be used by various users to access sites that have regional or connection restrictions.

How Do VPNs Work?

The way a VPN works is by encrypting data exchange before connecting publicly. Encryption is the process of turning information into a secret code to obscure data sent, received or stored on the internet network.

Someone using a VPN is tantamount to accessing the internet through a special network so that other people don’t know about it.

The VPN server will later be tasked with forwarding the connection to the destination site that you will access. So, the connection you make will be recognized as a connection from the VPN server network, not from the network used at that time.

Simply put, if you access a site without using a VPN, then your network connection will be made directly ( directly ) without the encryption process. However, if you use a VPN, your network connection will first go through an encryption process via the VPN server.
